Hierarchical microcontext technology and graph environment PYTHAGORAS

The research is devoted to a micro context approach to computer technology education and to engineering of languages and software. The main idea for education is to study at first not a large multiparadigm language (such as Pascal or Logo), but the set of orthogonal microlanguages. Then to decompose any development task into micro contexts; each of them can best be supported with its specific micro sub language and to input and to interpret such multilevel specification in composite media. This has to include a set of independent components; each serves a specific kind of work with a specific primitive microlanguage (editing, compiling, interpreting, etc.). We propose always preparing a large language when studying a hierarchy of micro sub languages. The approach is assisted by the PYTHAGORAS media. Characteristic features of the PYTHAGORAS are microlanguage technology support, and an inclination to a “game style” based work
